Bitcoin is the currency of the future

We don't make you choose between security and convenience. And we don't compromise your privacy.

Our per-transaction two factor authentication, multi-signature and deterministic wallet allow you unprecedented control over your transactions.

And, we never store your private keys, not even encrypted. At the same time we make it trivial to view and transfer your funds.

Take control of your future now, at GreenAddress.

Better privacy with your funds and safer login with watch-only

Safely check your balance and transactions from public Wi-Fi, Starbucks and on the go.

With our unique watch-only mode you can quickly check your balance or receive funds without full access to your wallet.

Your keys are not loaded so no transactions are possible and settings can't be modified.

More features that allow convenient and secure access to your wallet

Enable quick PIN login to your wallet from any of your devices without having to use your passphrase.

Should our system be taken down or disappear, sleep safe with our automatic presigned transaction (nLockTime) allowing you to simply wait for your selected expiry to get your funds!

All transfers to your wallet (including change) will use a newly generated address each time making it harder for people you transact with to read your past and future transactions.

Improved privacy

1) Hot wallets can be emptied and cold wallets may have delays, bugs or be lost 2) If the service is compromised brute force attacks may be tried on your encrypted wallet, requires strong password. 3) Access to user wallets requires that both the user and the service are compromised at the same time which reduces risks.

Under the hood

We use hierarchical deterministic wallets

(or BIP0032 HD Wallet) which means we use new addresses for each incoming transaction (including change), which, together with coinjoin (coming soon) allows you to maintain your privacy at the highest standard.

Quickly check your balance

You can use your custom username and password to quickly check if you have received a transaction or to check your balance without exposing your wallet, indeed quite convenient when in a hurry and/or on a third party computer.

We provide presigned transactions

In order to provide limits and two factor your funds are secured with both your key and ours. For ease of mind, presigned transaction are enabled (uses nlocktime) which means that each time your wallet has updates we will forward to you a presigned transaction unlocking the funds at a date in the future of your choice.

We use P2SH to make this all easy

P2SH allows people you interact with to handle transactions to and from GreenAddress' wallets transparently.

We offer our second signature

Which allows us to offer and enforce 2 factor authenticated payments and daily, weekly and monthly limits, rate limiting your transactions per hour, day, week and month and make your payment instant by providing a double spend checks with GreenAddress!
